Speaking tactically their are some casters/play-styles which favor the Brute over the Savage; Raider; and Shaman. it is also true that his effectiveness drops drastically in a game larger the 35 points, due to the larger number of ranged weapons that an enemy will bring to bare against the model(s) he is guarding.

For the most part the Brute is used to defend the more fragile casters as they are running up the field to slay the enemy caster. But any Skorne warlock more durable then Mekada will likely take a titan to simple block line of sight with its bulk rather then spend points on a light war-beast with a limited use.

p.s. There are at least three very scary unit combinations in the Skorne army that can make the cyclopes Raider a nightmare for any enemy, and they do not even need their warlocks to put this off.
